Can I use <iframe> in my emails?

An <iframe> (inline frame) embeds content from one website into another.

We don't recommend using it in emails. 

Inline frames are often used to insert advertisements, video, audio, or forms in other websites.

iframes often contain scripts and bad actors have abused this functionality in the past, so most email clients block them.

Instead, you can link to the content you want to display in your campaign.
